  1. Cell Size, and Cell Specialization Chap 7-1 & 7-4 http://www.parlament-berlin.de/Galeriecopy.nsf/0/8ABC720262898739C1256A480037F869?OpenDocumen http://www.ncu.edu.tw/~ls/graph/faculty_pictures/whole_time/SLC/SLC_lab-1.jpg t

  2. All living things made of cells BUT… organisms can be very different. Image from: http://www.agen.ufl.edu/~chyn/age2062/lect/lect_06/bacsiz.GIF UNICELLULAR MULTICELLULAR http://www.angelbabygifts.com/ http://www.inclusive.co.uk/downloads/images/pics2/tree.gif

  3. CELL SIZE http://facstaff.bloomu.edu/gdavis/links%20100.htm Typical cells range from: 5 – 50 micrometers (microns) in diameter

  4. How big is a micron ( µ ) ? http://www.talentteacher.com/pics/005cb.jpg 1 cm = 10,000 microns 1” = 25,000 microns

  5. They have different kinds of cells doing different jobs MULTICELLULAR ORGANISM don’t just contain MANY CELLS. Image from: http://www.isscr.org/images/ES-cell-Fig-2.jpg

  6. Cells in a multi-cellular organism become SPECIALIZED by turning different genes on and off Image from: http://www.ncu.edu.tw/~ls/graph/faculty_pictures/whole_time/SLC/SLC_lab-1.jpg Cell Specialization =DIFFERENTIATION

  7. SPECIALIZED ANIMAL CELLS Red blood cells Muscle cells http://www.biologycorner.com/bio3/images/bloodcells3D.jpg Cheek cells http://www.mlms.logan.k12.ut.us/~ajohnson/Cells.html
